Callen Walck is no stranger to swinging a baseball bat.

The Franklin Elementary student, who will be in first grade next year, has played in the Miracle League of the Lehigh Valley since he was 3 years old.On Sunday, Walck will be on the other side of the fence at the Russell "Bups" Ahner Memorial Old-Timers Softball Game in Franklin Township.The game, scheduled for 2 p.m. at Phifer Ice Dam Park in Franklin Township, is held each year to raise funds for local youth dealing with medical issues.Walck was diagnosed with Charcot-Marie-Tooth disease just before starting kindergarten.The hereditary disorder affects one in 2,500 Americans."It's recognized through the Muscular Dystrophy Association," said Callen's mother, Jamie."Basically, his muscles are fine, but the nerves throughout his nervous system are not sending the messages properly to his muscles," she said."So over time his motor skills will deteriorate. It's a very slow progressing form of muscular dystrophy."Wayne Wentz, who helps organize the game, said the children are selected in consultation with nurses at the respective schools.Though he wasn't officially diagnosed until age 5, Jamie said the family had noticed different symptoms since birth.The disease hasn't stopped Walck's passion for the game."He loves baseball," Jamie said."The Miracle League has been great for him because it's a league specifically for children with a disability. He's been doing really well."In Sunday's game, the Franklin Township "old-timers" will again be pitted against a squad from Jim Thorpe.Part of the game's tradition is to give the honoree a ride to the field in a firetruck, departing from the Franklin Township Fire Company."We haven't told him about it yet," Jamie said."He'd be asking about the firetruck ride every day so we're waiting until closer to the game."Over $115,000 has been raised through the event for sick or needy children."We were really shocked when we found out the game would benefit Callen," Jamie said."We don't go out looking for money to help us so it really caught off us guard."We're very grateful for the organizers for thinking of us."Rain date is Monday at 6 p.m.
